Small update...Added screws to each corner of the skeleton so I could set the side-to-side offset behind the cab:
then I cut a 2' x 8' strip of foamboard that would go from the cab and front-most x-section of the shell to the second x-section. With it centered behind the cab, I could start cutting to get a flush fit. Will have to get some better photos of this later.
And then had a first try at getting the panel to flex along the 3" radius curve that joins the sides of the shell and the top:
I started with lines 5/8" apart and about 5/8" deep, but found that this wasn't enough. I think I need to make them deeper and maybe do them every 5/16" instead.
Turbothrush, do you have any recommendations here, for forming around the 3" radius?
